What is one potential issue associated with infiltration in wastewater systems?

Infiltration in wastewater systems refers to the unwanted entry of groundwater into sewer systems. One significant issue associated with this is contamination from groundwater. Groundwater can carry various pollutants, including pathogens, heavy metals, and nutrients, which may enter the wastewater system as a result of infiltration. When this contaminated water mixes with the sewage, it can lead to more complex treatment challenges and can compromise the effectiveness of the treatment process. Additionally, if untreated or improperly treated, this contamination can affect water quality in receiving bodies of water, posing risks to environmental and public health.

Addressing infiltration is crucial to maintain the integrity and efficiency of wastewater treatment operations, highlighting why the issue of contamination from groundwater is a valid concern.
